If you use your computer for work or school or maybe just to run the family's budget, learning to fix computer problems can be extremely beneficial.

When your computers registry has been corrupted you may have error messages popping up on your screen such as "fatal .exe error" or ".dll file error" and these type of errors can cause your system to shut down or freeze up leaving you with a computer that you cannot use. When these type of errors occur it can be extremely frustrating because you may be in the middle of some important work so if your learn how to fix computer errors such as these you can avoid serious down time.

To fix computer errors that are related to your computers registry, you should complete a registry scan so that all the unused, old and unwanted data can be detected and removed. To clean your computers registry you will need to buy a good registry cleaner program. I want to emphasize on the word "Buy" because there are a lot of free registry cleaners available but it's a terrible idea to even try a free registry cleaner. Free registry cleaners will not only just not fix computer errors they will cause damage to your system. When it comes to the free registry cleaners the programmers will put in malicious code and adware and spyware programs that will collect and transmit your personal information and in many cases end up leaving your computer so damaged that it cannot be repaired.

Reg Clean is one of the more advanced registry cleaner programs available as it can perform a variety of preventative maintenance tasks as well as removing malicious spyware and viruses that have infected your registry.

They are capable of overwriting program files or deleting necessary file extensions disabling important programs and limiting the functionality of your system. To fix computer errors that are a result of spyware and some viruses you can use updated antispyware and antivirus protection.

Damaged or corrupt programs or virus infections can cause serious damage to your computers boot section, and this will prevent your system from booting up properly or possibly not at all. When you need to fix computer errors related to your system booting up properly you should use your Windows XP Boot CD as this can repair the Windows XP installation which can overwrite computer errors picked up through spyware or viruses.

If the problems that you are having are directly related to your computers memory you will experience some of the following problems; system crashes, system hang or computer freeze, blue screen, constant restarts and crashing software programs. To fix computer errors related to your systems memory there are specific software programs that can help free up some memory space which will help solve RAM related problems. Improving your systems memory which is also known as RAM (random access memory), will improve your computers performance dramatically so I would highly advice you to do a computer memory test. To complete a memory test there is specific software available for such a task, one program that I am aware of that is very effective is called Memtest86, this can help you zero in on your problem allowing you to fix computer errors brought to your attention.

If you have tried all the advice given in this article and your still experiencing computer problems I would do a search on the Internet for information on how to fix computer errors. You will find many websites that focus on computer basics and troubleshooting. I would be very careful though and really check the websites credentials so you can be sure that your getting advice from a reliable source. There is also a software program available that can help you learn how to fix computer errors but again I would be very cautious about any program that needs to be down loaded and run on your computer. Remember preventative maintenance can save you from a lot of unnecessary problems and one of the best preventative measures you can take is to purchase a reputable registry cleaner program and use it periodically.

How to Protect Your Computer From Viruses

2009-09-08T23:49:00.000-07:00

By Amy Nutt

With computers in almost every home and business, there is now an increased risk of acquiring computer viruses. A computer virus is a program that makes duplicates of itself and infects a users computer files. These viruses can spread from computer to computer infecting files and programs. Computer viruses are such a hazard because they can erase stored information and permanently damage files.

The following is a list of the many methods a user can implement to protect their computer from harmful viruses:

Make back-up copies of important documents and files and store them on a separate disk or external hard drive. By doing this, you will still have a copy of your files if your information is erased or the computer suffers other damage.

Use a quality anti-virus program that will scan files, programs, and software. Make sure you keep the anti-virus software up-to-date and scan your computer often. You can download anti-virus software from the web or purchase it from a store.

Do not share commercial software with anyone. It is an easy way to spread viruses. Make sure the software comes from a well-known and established source.

When you download files from the internet, make sure you scan them for viruses before opening and running them.

Watch out for spyware and hackers. Spyware programs are usually entwined with a download and will install itself onto a computer. The programs will monitor your search patters and relay the information back to the person who sent it. They can even acquire any stored financial information. Make sure you have a trusted firewall. A firewall is a program or hardware device that filters information coming through the Internet connection into your computer system. If incoming information is flagged by the filters, it will not be allowed through to your computer. It is also recommended that you expand your anti-virus protection to include anti-spyware, anti-hacker-tools (prevents hijackers from accessing your computer,) anti-key-loggers (protects your passwords,) and anti-worms. A worm is a small piece of software that uses computer networks and security holes to replicate itself and cause damage.

Block porn and spam using a spam filter program. These programs identify any suspicious emails and delete them before you open it. Some programs will even send an email back to the spammer saying your address is invalid.

Most viruses are triggered by opening an attachment. Don't open any attachments in an email unless you know the sender or the attachment has been scanned. If you are not sure about the attachment, delete it. A file with an extension like EXE, COM or VBS, is an executable program file. Once opened, it can run and do all sorts of damage to your computer. The best protection is to never open these executables that arrive in your e-mail.
If your computer is infected with a virus, use an anti-virus program to remove the virus and quickly get rid of all copies of the virus. If you need help, turn your computer off and take it to a professional who knows how to remove viruses.
It is important to remember that most viruses can be removed without permanently damaging your computer system. As well, most virus infections can be prevented. With proper anti virus protocols, you can protect you computer from harmful viruses.

90% Of Personal Computers Are Infected With Spyware Or Adware Programs, Is Your Computer One?

2009-09-07T20:46:00.000-07:00

By Tim Gorman

Latest estimates suggest that up to 90% of personal computers are infected with some form of spyware or adware program. It's important to stay alert and watch for signs of infection on your computer, because some of these programs can do some serious damage to your computer. Let's take a look at some of the main malicious software (malware) warning signs to watch for.

When you open up your browser, has your home page changed? If you go back in and change the settings back to your original choice, you may find that next time you open the browser it's changed again, usually to a different page from the last time. This is probably one of the most common indicators that you have spyware on your computer, so if this happens, get your system cleaned immediately.

Pop-ups are an annoying part of life on the Internet, but if you start getting pop-ups appearing that have your own name on them, be wary. If the pop-ups appear even when you're not connected to the Internet, or your browser is closed, then you definitely need to get your system checked.

Spyware often installs a new toolbar onto your computer system. So if a different browser or search toolbar suddenly appears, and you can't seem to get rid of it, you're most likely dealing with some form of malware at work. Even if you manage to get rid of it, chances are it will keep coming back unless you know exactly how to remove all of its files.

Perhaps you've just discovered that your Favorites list has been 'tampered' with. It may be that some new items have appeared that you don't recognize, or perhaps others have disappeared. If you delete them and they come back again, it's probably a spyware infection.

An infection of malware can often make your computer run really slowly. If you find that your system seems to run constantly at 100%, even when you have very processes operating on your computer, then it's likely your computer has been infected by spyware. Computer programs require a certain amount of free space to operate properly, so when spyware is chewing up all your resources, your computer may run at a frustratingly slow speed.

If you find you enter something into an Internet search bar, and instead of going where you expect you end up at an entirely different search engine, then it's likely malware has taken a hand.

Check your modem if you can, and see what the lights are doing when you're not actually using the Internet. If there are lights blinking, or something on your screen suggests that data transfers are occurring, be suspicious. Malware is probably sending or receiving information without your knowledge.

Unfortunately, there are also varieties of adware and spyware that don't alert you to their presence at all. So you need to check your system as a matter of routine, even if you don't observe any warnings signs of infection beforehand.

Don't let your computer become infected with spyware by visiting PC-Security-Guide.info where you will find helpful information and resources on email security, spam scams, spyware, adware and pc virus recovery tips that will keep your personal computer running virus free.

Removing Many of the Cables on Your Computer Desk

2009-09-05T16:39:00.000-07:00

By Jim Tonkins

For anyone who has an interest in computers and has more than a couple of devices, a computer table can be an unfortunate maze and mess of cables going in every direction. Not only is it unsightly, but it can also be confusing when you need to plug or unplug something as it's easy to grab the wrong cable and unplug something that is turned on! Many people are frustrated by the growing mess of cables and are choosing to adopt some of the increasing popular wireless technologies that are available today. The easiest thing is to get a wireless keyboard and mouse. This will eliminate two cables on your desk. Most of the keyboard and mice that don't have wires work over bluetooth these days and will require a bluetooth adapter in your desktop or laptop. It's also easy to eliminate your ethernet network cable by using a wireless network. In most cases, a wireless network is just as fast as a normal wired network and much more convenient. Some printers will even allow you to print over the wireless network or via bluetooth networking as well.

Other cables are going to be harder to eliminate. A power cable is necessary unless you are running off of battery power. External hard drives also need a USB or Firewire connection. Devices like a scanner and anything else that plugs in via USB will also require wires. Even though you can't eliminate these cables, you can organize them by running them in an organized fashion and by bundling up the extra cable so that it doesn't create a big confusing pile of colorful wires.

Solar Power Computers? Not a Bad Idea at All

2009-09-03T18:21:00.000-07:00

By Ara Pekel

A few technology bloggers once wrote that they do not trust solar power computers because they believe that computers operating on solar energy are not powerful at all. Naturally, with technophiles, the more powerful the gadget is, the more useful it is. Unfortunately, it also goes that the more powerful the gadget is, the more power it consumes.

Desktop computers are known to be big power hogs. They consume around 150 watts of power on the average, and that figure changes depending on the hardware installed on the computer. The power usage also goes up if the computer is kept on all the time.

However, is it really true that solar power computers will not provide the kind of flashiness that technophiles love? Two years ago, Lenovo proved that computers running on solar energy can be sexy too. Lenovo was definitely in the right direction when it launched its Blue Sky A61e PC two years ago.

This ThinkCenter PC model is lightweight at only 8 lbs, Energy Star 4.0 compliant, can run on only 45 watts, and can run on solar panels. Is it an ugly and clunky PC? Definitely not - with an AMD Athlon X2 Dual Core or AMD Sempron processor, 4 GB worth of RAM, and ultra-small hard drives that can go up to 750 GB worth of space, it is as sexy as most flashy, power-hog PCs go.

But you do not have to replace your existing computers with solar power computers if they are still running perfectly well. It is possible to run gadgets and appliances, even power-hungry desktops on solar energy. All you need to do is to buy two or three solar panels and use them to power up your home. The cost of one solar panel is only a small fraction of the cash you will cough up when you buy a computer.

Buying a Computer Online

2009-08-29T16:39:00.001-07:00

By Amy Nutt

Buying a computer can be a tricky prospect because there are so many things to consider before making the final purchase. You have to take into account how quickly technology changes and decide what you'll need to satisfy your computer needs for a few years. There are also some computers that are easier to upgrade than others which could factor into your overall decision. On top of the already confusing decisions, there are a lot of technical terms that explain how a computer works and if you don't know what they mean you could have no idea what you are buying. Shopping online for your new computer can help make things a lot simpler.

Most computer manufacturers have set up websites that make searching through their products easier than ever. You can decide whether you want a desktop or laptop and even choose from a list of possible things you will be using your computer for to narrow down your search. The options are usually casual computer use, work, and gaming and selecting from those choices will give you a list of computers that will already have the right components in them to do what you want to do. As an example, a gaming computer will have a better than average graphics card and more RAM, both of which are needed to play games.

Shopping for a computer online also gives you more personalized customization. You can choose the color of your computer, although some websites will give you more options than others. You can also upgrade the components yourself so that you get exactly what you want. Most manufacturers will have steps through the possible upgrades directing you to the part of the computer that can be upgraded and what options they have for it. You may even be able to get software pre-installed on your computer from programs like Photoshop to the latest Call of Duty game.

Customer support is also an added benefit of buying a computer online. Unlike going to a store where you may have to compete to get the attention of one of the employees, websites have multiple people online and ready to help you with any questions you might have about your new computer purchase. Often the customer support will be available as a chat window that you can look at while going to different sections of the website, making it possible for you to discuss specific things about what you are looking at.

Every website that sells computers has specials going on all the time and you can take advantage of the ones that work for you. Usually they are discounts or free items such as a printer when you buy a certain model computer. Since most of the models are upgradeable then you will be sure to get a good deal. Once you've got everything you need in your cart you can pay online with your credit card through a secure area and have your computer shipped right to your door in as little as a few days.

Canadian Online Shopping offers reward points on all online purchases made at participating retailers sites. From clothing to Dell Computers, choose from over 45 band-name stores.

Buying a Computer Mouse - Four Things to Consider

2009-08-28T02:51:00.000-07:00

By Jeffrey Frasco

Clicking on a computer mouse comes as naturally as typing on a keyboard for many desktop computer users. A mouse is a very effective way to navigate onscreen and much faster than navigating via touch pads on laptop computers. If you are using a notebook computer, you will likely get weary using a touch pad with your sweaty fingers on a hot summer day. Treat yourself to a computer mouse and navigate faster with more seamless cursor movements!

Here are some things that are helpful to consider when selecting a computer mouse.

* Type

There are two types of mice: the mechanical mouse and the optical mouse. The mechanical mouse is your old ball mouse which uses a ball to detect movement on a mouse pad. An optical mouse uses a light-emitting diode (LED) in place of the mouse ball and can be used on any flat, opaque surface.

Optical mice are more advanced than mechanical mice and easier to maintain and use. With an optical mouse, you no longer have to worry about dirt and dust clogging the ball in a mechanical mouse. In addition, you can use your optical mouse without a mouse pad so long as you place your optical mouse on top of a flat and non-reflective surface. If you place your optical mouse on an uneven surface that creates a glare, these bumps and glares will cause the LED light to refract and your optical mouse will not be able to accurately interpret your movements.

* Speed

Speed in mice is measured in dpi or dots per inch. The larger this number, the faster your mouse is. If you frequently play computer games, you will appreciate a high dpi mouse' immediate response to slight movements. A mouse at 800 dpi is a good computer peripheral to own, but some computer users are perfectly happy with a 400 dpi mouse.

* Size

Computer mice come in a variety of shapes and sizes. Some are large and meant for large hands. Others are small and specially designed with children in mind or people with small hands. When shopping for a mouse, make sure that it fits comfortably under your palm as you will be spending a lot of time with it.

* Connectivity

You can attach a mouse to your computer using a serial port or USB port. Many USB mice come with a serial port adapter so you have the option to plug your mouse in a serial port. It does not really matter where you attach your computer mouse. To the naked eye, USB and serial ports both offer the same functionality when it comes to mice.

The computer mouse will be a constant computing companion for you so be certain to pick one that is comfortable and easy to use.

How Important Is A CPU Fan?

2009-08-27T00:12:00.001-07:00

By Victor Epand

The computer may look like a very powerful and intelligent device but without the help of the various parts, the computer is absolutely nothing. We all know about the hardware and software parts of a computer but among them also there are such minute things which do not comes in our notice easily but are something very indispensable. These are very small and useful objects which sometimes prove to be very important for even performing the major tasks.

In this context, variety of things being used in the PC can be uttered like the RAM, hard disk, CD ROM, motherboard, CPU fan etc. Let us pick up one object from among these and discuss widely how important even the minute parts of the computer are.

The use of the CPU fan perhaps could have been denied but that is not possible. CPU is the most important organ of the computer without which the operating system can not be run. It is the CPU that makes the computer operator to write, store, send, download and make project etc. very easy. What does it take to make your tasks happen? Stating them is the first step towards its realisation, the realisation of the importance of the CPU. For the CPU to run what is vital is the CPU fan.

The CPU fan is the most simple and ultimate thing that keeps the CPU cool and workable. Due to the excessive pressures and heat, the CPU becomes very hot and under such circumstances it is the CPU fan that makes the CPU capable of working properly. This small part is fixed in the inner part of the CPU and starts working as soon as the CPU is started.

The CPU is a combination of a number of parts namely the motherboard, memory, the arithmetic and logical components etc. the task that is performed by these components of the CPU are no doubt the very important ones. Therefore when all these will work continuously and together, it is very natural that these will get a high temperature. Probability is also there of these components being burned due to extreme heat and work load. In order to keep them cool and to give them sufficient air to cope up with the situation, the CPU fan is a must.

The price of the CPU fan, if bought alone and not altogether as a CPU, will be less. Based on the function and size though it is very important, but still there are facilities of availing these in reasonable prices. The used CPU fan is also another thing that can be had in very low prices and that too in workable conditions.

For a computer user the importance of the CPU fan is not at all a new thing to describe and he also is well aware of the utilities of this hardware part. Therefore from now onwards you too can lower the price of your computer parts to make your computer purchase in a reasonable rate.

Victor Epand is an expert consultant for computers, laptops and software. When shopping for used computers, used laptops and used software, we recommend you shop at only the best online stores for used CPU fan, used CPU fan, used CPU fan software.

Choosing a Laptop Computer

2009-08-25T20:48:00.000-07:00

By Matt C

A laptop computer can be a highly-productive, entertaining and useful piece of technology to own. Buyers beware though, as these tech toys can cost thousands of dollars, depending on which model you go for. Generally, Macintosh or Apple laptop computers are pricier with less room to go on sale. Other brands of PC will tend to have more margin for sale pricing, and you can scoop up a great deal by shopping online, checking weekly sale inserts in the newspaper, or stopping by your local electronics store. Before you go about choosing a laptop computer, you should know the basics though.

The basic specifications you'll want to pay most attention to for your laptop computer are the processor speed (CPU), memory (RAM) and hard drive storage space. The computer processing unit (CPU) is what determines how fast your computer runs and processes tasks. Usually this is measured in total gigahertz. You can usually go with a Core 2 Duo processor, or one with 2 gigahertz of CPU at least, to be able to have the latest , up-to-date technology. Intel makes top of the line CPU's while AMD and Celeron processors are also well known.

The memory in your laptop computer, often known as "RAM", will play a part in how many tasks or programs you can run at once. The higher the amount of memory, the more your computer will be able to handle doing. These days it's smart to get a laptop with at least 2 gigabytes of memory, or as much as 4 gigabytes. These computers will adequately handle all your tasks at once. When it comes to storage of all your files, photos, music, videos and other data, the hard drive is what will hold all of that as well as your laptop's programs. The higher in gigabytes (or even terrabytes) that the hard drive is, the more data it will be able to hold. A hard drive with at least 250 gigabytes will provide plenty of storage for the average laptop user. If you feel you'll be downloading a lot of music or storing lots of pictures and videos, consider getting more. You can always add an internal or external hard drive later for more data storage, so keep that in mind should you want to expand.

Shopping for a laptop computer shouldn't have to be a daunting task. While most people view technology with trepidation, you can head to the store with the basic knowledge you need to make your buying decision. Other considerations will include the extras such as webcam, internet, input/output ports and what sort of CD or DVD drive the laptop has. These will come down to personal preferences, so make sure to draw up your list of what you'll need before you shop, so you can be more than ready to make an informed purchase.

Types of Computer Crimes

2009-08-24T07:55:00.000-07:00

By Pauline Go

Computer crimes refer to the use of information technology for illegal purposes or for unauthorized access of a computer system where the intent is to damage, delete or alter the data present in the computer. Even identity thefts, misusing devices or electronic frauds are considered to be computer crimes.

Here is a list of different types of computer crimes.

• Hacking: This involves gaining unauthorized access into a computer system. Usually hackers are able to get through the security capabilities of a computer system and once they are in, they have unlimited access to confidential information and data stored in the computer. Today, hacking of IP addresses is very common as it allows the hacker to assume a false online identity and conduct criminal transactions without revealing his true identity.

• Phishing: This is a common computer crime is the United States. Here emails are sent to gullible users that make them believe that the emails are from authentic sites. The users are passed onto fake websites where they enter their confidential data like usernames, passwords and credit card details. The fake websites look and feel real and that is why many people get fooled into entering sensitive information.

• Computer Viruses: These are actually computer programs that are capable of replicating themselves and harming computer systems present in a network. These viruses work without the knowledge of the users and spread from one computer to another through the network, Internet or removable devices like CDs and USB drives. Writing computer virus is a criminal activity and is punishable by law.

• Identity Theft: This one of the most serious frauds in today's word. It involves stealing money and getting benefits by using an identity of another person. This also includes the use of someone else's credit card details to purchase good and services. It has been seen that blackmail and terrorism often employ identity theft.

• Cyberstalking: This is using the Internet to stalk a person just like someone world do in the real world. Here the stalker sends emails, spreads false information or issues threats using the Internet. Cyberstalking is also used to prey on unsuspecting children and women.

Computer Memory - How Much Do You Need?

2009-08-22T18:43:00.000-07:00

By Yung Trang

In life, it is often said that "you can never have too much of a good thing." Apparently, this is not so when it comes to RAM (Random Access Memory - also referred to as simply "memory" or storage) for your laptop or computer! No need to spend money on extra RAM that your system cannot utilize. (You can easily check the specifications of the system you are considering by asking how much memory is already installed, and what the maximum memory capacity is for the system.) But how can you be certain you have enough computer memory not only for your current needs, but for what your future needs may be, too? Let's start at the beginning...how much computer memory do you need?"

When buying a computer or laptop, the available memory on that system should be a primary consideration, because the more you do, the more memory you need! The applications you use dictate how much memory you need for the best possible performance, the smoothest graphics and the speediest downloads. RAM is used every time you open an application, download, play a game or video - even turning on your computer requires RAM.

Peripherals such as webcams, digital cameras, DVD players and USB hard drives require more RAM. These requirements, coupled with complicated web pages and PC-based video games may surprise you in that you have significantly less RAM than you thought. Therefore, buy the most RAM you can afford; more RAM makes for a speedier computer. Today, available PC systems range from 512MB (which is the bare minimum) to 4GB of memory.

If you already have a computer and are considering a memory upgrade, review the manuals that came with your computer or motherboard. Included in the documentation are the specifications for the memory supported. This is important because it will list exactly the type, size and number of memory modules that are supported. (Most retailers and/or manufacturers have this information, too.)

Buy as few modules as possible for the amount of memory you want to install; this will aid in future system upgrades. (For example, if you have 3 memory slots on your computer, one of which has a 1GB module in it, it is smarter to buy another 1GB module to get to 2GB of total memory verses purchasing two 512MB modules.)

To give you some idea of RAM requirements, according to a 2009 pcstats.com article, Windows Vista Basic requires a minimum of 512MB, though they advise that realistically, that number should be doubled. In fact, the article states that "Vista will function with 512MB system RAM, but the ride is a rough one!" While Microsoft recommends Vista computers ship with 1GB memory, 2GB of RAM is generally considered the best option for Windows Vista.

The easiest ways to boost performance for any PC is to add memory (RAM) to the system. Before purchasing that memory upgrade, however, remember to verify what type of memory your computer uses, the memory module sizes and what already exists in the system. If you are buying a new system, look for the maximum RAM available.

Five Steps to Buying a Computer

2009-08-21T02:39:00.000-07:00

By Jonathan J Waller

If it's your first time buying a computer and stepping onto the computer field, finding a new upgrade from your old one, or just want another PC then this guide is great for you! Many people see buying a new piece of technology they have no knowledge about scary, especially a computer. There are so many things to take into consideration! When first heading into a PC store down the street you may get completely confusing terms by a salesperson. How much ram do you need? How much hard drive space? How fast do you need the processor to be? Do you want a good video card?

With all these questions one must wonder if they are getting what they need. Is this guy telling the truth? Or is he selling me a piece of garbage and I don't know the wiser. For starters, the more informed you are the better decisions you can make on your purchase. Follow these steps to prevent making the mistake of buying the wrong computer.

Make a decision on what your computer is going to do. Figuring out what purpose your computer is going to be used for will help you eliminate other ones with extra functions that you do not necessarily need and will cost you more money. Will you be using this computer for E-mail? Internet Browsing? Games? Homework? Work? Music/Videos? Computers can do all these things and much, much, more. So deciding what your computer needs to do is extremely important.
Find the proper software that can accomplish your needs. Find out what software you want to help you do your homework, such as Microsoft word, excel etc. Although many people may get confused why software first? You must find out what requirements the software has to run on the system. With proper research you can find out what specifications your computer needs.
Find the computer that can run your software. Make sure that the computers hardware spec's are fast enough and meet the needs to run a program properly. If your going to play games on your computer then you are going to need a more high end machine but if all you are doing on is browsing the Internet a less costly PC can be purchased.
Find a PC with good customer support and a warranty. Many computers, especially used ones do not offer any support or a long warranty! What if you can't figure out how to stop to get a program to run? What if your PC all of a sudden will not turn on? With no service you are left to figure it out yourself causing unneeded headaches.
Buy your new computer. If you took all the proper precautions, don't sit around and hesitate to buy the computer. You researched properly! Buy the computer don't worry it will be fine.

With this information you should be able to avoid scams, tricks, and misinformation from sellers.
